Whopity, the rating is being renewed, outside the 5 year period, not added. Re. the ANO, the PPL would not fly without adhering to your quote, ie a class 1 or 2 medical to use his SEP rating.
Also you mention advice to examiners. To quote the FE handbook ,sect. 2.3.2
"Checks and tests for rating issue, renewal or revalidation may be carried out on individuals whose licence or medical is out of date......Certificate of revalidation can still be signed if appropriate ,but a marginal note of the expired medical made on SRG\1119"
To my knowledge there is no NOTEX saying the opposite of this , given this was the 2010 FE handbook approved by the CFE!
Given the above, why can't the CAA follow their own advice and issue a rating irrespective of the medical status. As they are now effectively a regional office of EASA, why introduce more complication?
